Where can Epithelial Tissue be found and what does it constitute?
covers body surface, lines body cavities, forms internal/external organ linings, and constitutes most gland tissue
What are the 5 distinct Properties of Epithelial Tissue? (CRAP-A)
Cellularity, Regulation, Avascular, Polarity, Attachment
What is the difference between microvilli and Cilia?
Microvilli is surface area folds for absorption and Cilia are tiny hairlike features that provides locomotion
What is Simple Squamous Epithelial Tissue and where can you find it?
single layer of flat "scrambled egg-like" cells in contact with the basal lamina
usually found in lining of vessels and heart
What is Keratinzed Stratified Epithelial Tissue? Where can you find it?
covered in a layer of dead, compact, squamous cells packed with durable protein keratin and coated with water repellent glycolipid
thus, retards water loss and resists penetration by disease organisms
Skin is made up of this
What is NonKeratinized Stratified Epithelial Tissue? Where can you find it?
lacks surface layer of dead squamous cells
thus, abrasion resistant and must be kept moist by body secretion
Found in Anal Canal and Vagina
What is Simple Cuboidal Epithelial Tissue? Where can it be found?
single layer of squarish/round cells
provides absorption and superb secretion properties
found on the surface of the ovaries, lining of nephrons, part of eye/ thyroid
What is Stratified Cuboidal Epithelial Tissue? Where can if be found?
multiple layers of squarish/round cells
found on the lining of large ducts and glands
What are Glandular Epithelial Tissue? What are the two types?
Cuboidal Epithelia that produces secretions
Endocrine and Exocrine
What are exocrine glands? What are their classifications?
discharge of secretion to epithelial surface via ducts
serous, mucous, and mixed
What are Mucous Exocrine Glands? Example?
Secrete mucin protein that absorbs water and creates slippery mucus
mucus in saliva
What is Simple Coiled Tubular Exocrine Gland? Where can one be found?
single unbranched duct and a secretory portion of uniform diameter, coiled
Merocrine Sweat Glands
What is Simple Tubular Exocrine Gland? Where can one be found?
single unbranched duct and a secretory portion of uniform diameter
What is Simple Branched Tubular Exocrine Gland? Where can it be found?
single, branched duct and secretory portions of uniform diameter
Gastric Glands, Mucous Glands, Tongue, Duodenum
What is Simple Branched Alveolar Exocrine Gland? Where can it be found?
Branched duct with dilated sacs
What is compound Tubuclar? Where can it be found?
Many Branches of uniform diameter
Tested, Bulbourethral Gland, Mucous Gland
What is compound Tubuloalveolar Exocrine Gland?
gland with tubular cells in both, tubular and acinar portions
Salviary Glands, Pancreas
What is Endocine Gland?
discharge secretion in surroundings without ducts
secretes hormones into the blood
What are the three modes of secretions?
Merocrine (Cellular Sweating), Aprocrine (Head Explodes, releasing secretions, then regenerating), and Holocrine (whole cell explodes, releasing body and secretions, stem cells create new one)
What is Simple non ciliated Columnar Epithelial Tissue? Where can it be found?
single layer of tall, narrow cells
provides protection with absorption capabilities
What is Simple Ciliated Columnar Epithelial Tissue? Where can it be found?
hairlike structure on the apex of the Simple Columnar Epithelial Tissue, provides locomotion
fallopian tubes, uterus, upper respiratory tract
What is stratified columnar epithelial tissue? Where can it be found?
multiple layers of tall, narrow cells
used for secretion and protection
anal canal, pharynx, larynx
What is Pseudostratified Epithelial Tissue? How can it be identified? Where can it be found?
every cell reaches the basal lamina and is identified by it's zigzag nucleus
contains "Goblet Cells" filled with mucus coating to protect mucus membrane found in upper respiratory passageways
What is Transitional Epithelial Tissue? How can they be identified? Where can they be found?
Stretches and changes shape
non usually ciliated
Contains all epithelial tissues, which is strange because they don't like to hang out
What are the classifications of Connective Tissue and their consistencies?
Connective tissue Proper (syrup like)
Fluid Connective Tissue (watery)
Supporting Connective Tissue (dry cement-like)
What is Connective Tissue?
connects structures, provides support and protection, fills space between structures, stores fat, defends from infection, and repairs tissue damage
What are the types of fixed cells in Connective Tissue Proper?
Fibroblast, Fixed Macrophage, Adipocytes, Mesenchymal, and Melanocytes
What are Fixed Fibroblast cells of Connective Tissue Proper?
Star Shaped cells that are responsible for production of CT fibers and secretes Hyaluronan, which forms the syrupy ground substance
What are Fixed Macrophage cells of Connective Tissue Proper?
Responsible for engulfing damaged cells that enter the tissue and touches it, then releases chemicals that activates the immune system
What are Fixed Melanocyte Cells of Connective Tissue Proper?
synthesize and secrete melanin, which is responsible for skin color and protects skin from UV Radiation
What are Free Macrophages of Connective Tissue Proper?
arise from white blood cells and engulfs bacteria
What are Mast Cells of Connective Tissue Proper?
secrete histamine and heparin, which stimulate inflammation
What are Lymphocytes of Connective Tissue Proper?
forms into plasma, which synthesizes Antibodies,
found in intestines/inflamed tissue
What are Microphages of Connective Tissue Proper?
Neutrophils and eosoniphils
secretes chemical to attract mast cells
What is Collagen Fiber of Connective Tissue Proper?
made up of Collagen Protein, then makes up tendons and ligaments
What is Reticular Fiber of Connective Tissue Proper?
creates spongelike framework for organs such as spleen and lymph nodes
What is Elastic Fibers of Connective Tissue Proper?
creates elasticity of the skin, lungs, and arteries,
made up of Elastin Protein
What is areolar tissue? Where can it be found?
loosely organized fibers, abundant blood vessels, and contains Fibroblasts, Macrophages, Adipocytes, Microphage, Mast, Lymphocyte cells
found pretty much everywhere
made up of mostly ground substance
What is Reticular Tissue?
mesh of reticular fibers and fibroblasts
forms structural framework of organs
What is Dense Regular Connective Tissue? What are some examples?
composed of collagen fibers aligned in parallel protein o applied force
Tendons, Aponeuroses, Elastic Tissue, Ligaments
What is Dense Irregular Connective Tissue?
interwovan mesh work that do not have a consistent pattern
What is Supporting Connective Tissue? What are some examples?
dry, cement like ground substance
Cartilage and Bone
